similar to: adjust labels in plot:terminal_panel {party}

Hi, I am trying to get the terminal nodes of a plot of a ctree object to look nice. Using the iris data I have: library(party) mtree <- ctree(Species ~ ., data=iris) plot(mtree,terminal_panel=node_barplot(mtree)) The terminal nodes don't display the species names because the names are displayed horizontally. ?I would like to reduce the size of the labels and make the terminal nodes

Hi All, i've got a problem using the ctree function of the party package. I've searched around a lot but couldn't manage it. I've got an ordered factor as response. As far as i know i have to use scores to be able to use this ordered factor. But if i do so i get a tree which predicts all observations as the first level of my ordered factor. In order to test if i did anything

Hi List, I am trying unsucessfully to modify the fontsize of lables in mosaic: require(vcd) mosaic(Titanic, pop=FALSE, labeling_args=list(rot_labels=c(bottom=90,top=90), set_varnames = c(Sex = "Gender"), gp_text=gpar(fontsize=20))) #can't get it to resize text tab <- ifelse(Titanic < 6, NA, Titanic) # it works for labeling_cells labeling_cells(text = tab,

Dear all: Is there a way to add text to the margins or outer margins of a mosaic plot using the vcd package? I understand the margins argument to mosaic, but I don't know how to add text to that. I'd like to add a caption to a plot. If possible, I'd like to know how to set the font and size for that function as well. My plot looks roughly as below. Thank you for your time! Simon J.

Hello, I plotted a nice tree with "ctree" . It shows 3 nodes with the prediction of my 2 groups. (see picture) Unfortunately I need a larger scale to read the exact prediction of my groups to get the specificity and sensitivity. I tried to change the scale with "axis" but it didn't work, my guess because it's not a normal graph with x and y axis. Has someone an idea

I try tu use mob() with my data.frame ('data.frame': 288 obs. of 81 variables; factors, numerics and ordered factors) My response is a binary variable and I should use for modelling a logistic regression (family=binomial). I read in the "MOB" Vignette that I could use a formula like this if I would like to have only partitioning variables apart from the response.

Hello All, I am using library "party" and I have found a curious/strange behaviour when trying to save the output of a ctree in a file via jpeg/png command. If you use: ################ library(party) airq <- subset(airquality, !is.na(Ozone)) airct <- ctree(Ozone ~ ., data = airq) plot(airct, terminal_panel = node_boxplot, drop_terminal = FALSE) ############### you get a

Hi, hackers : Yesterday night and this morning, I cvsup my system to latest STABLE branch source (RELENG_4). All make buildworld, buildkernel, and installkernel procedure was completed with no error. But when I boot into single user mode and try to make installworld, I always got " touch: not found " error. Does anyone encounter this situation ? I have no idea about that. :-( Here is

Hello, I'm trying to use the vcd package to analyze survey data. Expert judges ranked possible features for product packaging. Seven features were listed, and 19 judges split between 2 cities ranked them. The following code (1) works, but the side-by-side plots for Cities PX, SF are shrunk too much. Stacking PX on top of SF would make for a better plot. (I could switch the order of

Hello, I've sent a similar query before, but didn't receive any answers. When upgrading from 9.1 to 9-STABLE, the buildworld fails with: ===> usr.bin/xinstall (all) cc -O2 -pipe -I/usr/src/usr.bin/xinstall/../../contrib/mtree -I/usr/src/usr.bin/xinstall/../../lib/libnetbsd -I/usr/src/usr.bin/xinstall/../../lib/libmd -std=gnu99 -fstack-protector -Wsystem-headers -Werror -Wall

I'm trying to find a way to change the font size in a mosaic plot (the grid version, not the base graphics one). Here's an example to demonstrate: #Basic plot library(vcd) mosaic(HairEyeColor, shade = TRUE) #Bad first guess: this stops the default cell colouring, and doesn't change the font size mosaic(HairEyeColor, shade = TRUE, gp=gpar(fontsize=16)) #This successfully changes

Hello, I've been using ctree and have developed a 55 node - 28 terminal solution. As can be imagined, the plot is difficult to travel down each of the major branches. I've read the help files for ctree I saw where terminal nodes can be color coded. plot(airct, type = "simple") > plot(airct, terminal_panel = node_boxplot(airct, col = "blue", + fill = hsv(2/3,

I'm trying to use the vcd package to produce mosaic plots for my class notes, written in Sweave and using the LaTeX's beamer document class. For projecting the notes in class, I use a dark background with light foreground colors. It's easy enough to change the defaults for R's standard graphics to match my color scheme (using the fg, col.axis, col.lab, col.main, and col.sub

helpeRs, I have a nice looking mosaic plot in an article to be published soon. Sadly, the published version will be in black and white and so ruin the advantage of the default shading scheme of tiles. What would readers suggest as an alternative shading scheme? If I have a black-and-white shading scheme graduated according to suitable cutoffs I won't be able to tell positive from

Hi all. This might seem really naive, but can mtree be used effectively as a native-to-core-OS tripwire equivalent? Would it be as efficient in terms of time-to-run and resource requirements? What sort of pitfalls should I be aware of? Has anyone here done this? If so, would you care to share your scripts/techniques? Thanks, Dave -- ______________________

I'm working with the following code below to generate a how do I set the h,c, and l values such that the significant, positive residuals appear different on a grayscale printer from significant grayscale residuals. The challenge as I see it is that one can only distinguish the positive and negative residuals with the hue/. Varying the chroma and the luminance only affect the

Hi there, I need to extract the variable names from all nodes (except the terminal nodes) from a ctree object, e.g. library(party) mammoct <- ctree(ME ~ ., data = mammoexp) plot(mammoct) how can I extract the varnames from node 1 (SYMPT) and node 3 (PB) from the fitted object "mammoct"? Many Thanks, Sven
